• an embroidery cloth feeding unit attachably and detachably mounted to the free lower arm and including a horizontal wall engaged with a lower side of the free lower arm;
• a moving member installed at a lower portion of the free lower arm and moved by mounting the embroidery cloth feeding unit;
• and
• a horizontally moving mechanism driven by movement of the moving member for upwardly and downwardly moving a feed dog of the sewing machine, wherein the horizontal wall includes a contact portion constituting a portion of the horizontal wall and moving the moving member by being brought into contact therewith when the embroidery cloth feeding unit is mounted to the free lower arm.

A sewing machine having a free lower arm, said sewing machine comprising:

• a manually switch switchable between a first position and a second position;
• a vertically moving mechanism for upwardly and downwardly moving a feed dog between an elevated position and a lowered position by switching the switch;
• an embroidery cloth feeding unit attachably and detachably mounted to the free lower arm;
• and
• a moving member installed at a lower portion of the free arm moved by mounting the embroidery cloth feeding unit, wherein the switch is switched to the second position by being pressed by movement of the moving member when the embroidery cloth feeding unit is mounted to the free lower arm.

A sewing machine, having a bed, a free arm extending from the bed, a pedestal extending upwardly from the bed, and a sewing arm extending from an upper end of the pedestal over the free arm in an opposing relationship, comprising:

• a feed dog movable in an opening in an upper surface of the free arm;
• a first feed dog movement mechanism housed in the bed and an extending free arm that moves the feed dog between an operating position and a recessed position below a surface of the free arm;
• a second feed dog movement mechanism housed in the bed and an extending free arm that moves the feed dog in a forward and rearward reciprocating motion;
• a switch operatively linked to the first feed dog movement mechanism movable from a first position where the feed dog is in the operating position and a second position where the feed dog is recessed;
• a feed cloth moving member that removably mounts to the free arm for embroidery sewing;
• a moving member mounted in the bed and having a contact portion extending out of the bed, the moving member shifting the second feed dog movement mechanism from the first position to the second position when the feed cloth moving member is mounted to the free arm, the moving member position observable by an operator.
